BimmerWorld View - CSF provides a high-quality that exceeds OE standards, gets rid of the plastic end tanks, and improves cooling by 25-30%. Drop-in fitment and more efficient cooling for your street/track car at a great price.
We trust CSF quality and performance in our street and track cars to provide proper cooling with an easy direct-fit install.
This E46 radiator is a factory replacement using all factory shrouding, clip-on hoses, and mounting points.
CSF uses new technology packed into a compact two-row core design for better cooling capacity without the added weight. More efficient B-tubes have greater surface area for cooling (15% cooling capacity increase in fin technology alone) and a precision multi-louvered fin to increase heat rejection performance and surface area contact. Additionally, this CSF part has more total cooling tubes, and due to the efficient B-Tube shape, airflow through the core is improved as well. These technical features all contribute to improved cooling efficiency over OE-type performance upgrades, as well as other standard "performance" aluminum tanked radiators which are nothing more than aluminum tanks on a traditional stock core.
Made in Indonesia in the same factory that produces CSF parts for aftermarket and car line production for several European cars. All CSF radiators come with a two year warranty against defects in craftsmanship.
Fits all 99-06 E46 6-cylinder models (320, 323, 325, 328, 330), and 05-05 3L Z4.
